Description

Double-sided climbing self-standing step ladder with double platforms

technical field

The utility model relates to a double-side step ladder folding ladder, in particular to a double-side climbing self-supporting step ladder with double platforms.

Background technique

The existing double-sided and single-sided self-supporting step ladders on the market will be equipped with a self-locking mechanism, which will maintain its working angle when the ladder is opened and prevent the two parts of the ladder from sliding outward or closing inward. The self-locking mechanism Often there is one place on the left and right sides of the ladder and it functions independently. Therefore, when the aluminum ladder needs to be folded, the iron sheets on the two mechanisms must be lifted up to make it rotate at a certain angle before the ladder can be folded. The operation is troublesome. Moreover, when the ladder is in the self-supporting open state, even if the user is on the ladder, its self-locking mechanism will not directly bear the load and bear the force. Risky, especially when the user is at the top of the ladder. In addition, most of the above-mentioned self-supporting step ladders are only provided with a standing platform, and even some ladders are not provided with a standing platform. Like this, the use of the ladder has certain limitations and brings a lot of inconvenience to users.

One end of the two standing platforms is hinged with each other, and the other ends of the two standing platforms are respectively connected to the left and right columns of the corresponding ladder. On the basis of the original single-platform double-side climbing self-supporting step ladder, an additional standing platform is added, and the limit hinge between the two standing platforms makes the standing platform have a self-locking function. There are standing platforms at the front and back of this self-standing step ladder, which is safer to use. At the same time, the standing platform can be used as a self-locking mechanism when the self-standing step ladder is opened. When the self-standing step ladder needs to be folded, just put the two standing Only one limit hinge of the platform can be lifted up, instead of the self-locking mechanisms on the left and right sides needing to be lifted up as in the prior art, in order to better realize the folding.

The front standing platform is provided with a front shaft and a front cantilever, and the rear standing platform is provided with a rear shaft and a rear cantilever. The rotating shaft is rotatably connected with the column of the front ladder, the rear rotating shaft is rotatably connected with the column of the rear ladder, and the front cantilever and the rear cantilever are limit hinged.

The front cantilever is composed of a first top plate and a first side plate, the first top plate is located at the top of the first side plate, the rear cantilever is composed of a second top plate and a second side plate, the second top plate is located at the top of the second side plate, The first side plate of the front cantilever and the second side plate of the rear cantilever are hinged to each other, and the first top plate of the front cantilever is stacked on the second top plate of the rear cantilever.

The left and right sides of the front standing platform are all provided with a front rotating shaft and a front cantilever, and the left and right sides of the rear standing platform are all provided with a rear rotating shaft and a rear cantilever, so as to improve the stability of its connection.

The top of the ladder is provided with top pedals, and the upper ends of the two ladders are connected by rotation through the two top pedals.

The standing platform is located at a height between the top pedal and the fixed pedal.

The beneficial effects of the utility model are as follows:

This double-sided climbing self-supporting step ladder with double platforms adds an additional standing platform on the basis of the original single-platform double-sided climbing self-supporting step ladder, and the limit hinge between the two standing platforms makes the standing platform have a self-locking function; When the user needs to change the working position to the other side of the ladder, it is no longer necessary to move the ladder to the side where the platform is located; in addition, when the ladder is retracted, it only needs to be lifted up on one side at the connection between the two platforms. The ladder can be folded after reaching a certain angle, which is convenient to operate.
